Chain Warnings:
Caution: It must be recognized that certain factors in the usage of chain and attachments can be abusive
and lessen the load that the chain or attachments can withstand. Some examples are twisting of the chain,
disfigurement, deterioration by straining, usage, weathering and corrosion, rapid application of load or jerk-
ing applying excessive loads, and sharp corners cutting action.
Due to the crushing effect Grab Hooks have upon chain, the design factor of all assemblies must be
reduced by 20% for Grab Hook applications.
